Marie Curie was a Polish physicist and chemist who lived between 1867-1934. Together with her husband, Pierre, she discovered two new elements (radium and polonium, two radioactive elements that they extracted chemically from pitchblende ore) and studied the x-rays they emitted. She found that the harmful properties of x-rays were able to kill tumors. By the end of World War I, Marie Curie was probably the most famous woman in the world. She had made a conscious decision, however, not to patent methods of processing radium or its medical applications.

Marie Curie was born November 7, 1867 in Poland and died on July 4, 1934. Her co-discovery with her husband Pierre Curie of the radioactive elements radium and polonium(钋) represents one of the best known stories in modern science for which they were recognized in 1901 with the Nobel Prize in Physics. In 1911, Marie Curie was honored with a second Nobel Prize, this time in chemistry, to honor her for successfully isolating pure radium and determining radium's atomic weight.

As a child, Marie Curie amazed people with her great memory. She learned to read when she was only four years old. Her father was a professor of science and the instruments that he kept in a glass case fascinated Marie. She dreamed of becoming a scientist, but that would not be easy. Her family became very poor, and at the age of 18, Marie became a governess. She helped pay for her sister to study in Paris. Later, her sister helped Marie with her education. In 1891, Marie attended the Sorbonne University in Paris where she met and married Pierre Curie, a well-known physicist.

Marie Curie contributed greatly to our understanding of radioactivity and the effects of x-rays. She received two Nobel prizes for her brilliant work, but died of leukemia(白血病), caused by her repeated exposure to radioactive material.

Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That's every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles.”
